IMPROVEMENT IN REGISTERS.

Specification forming part of Letters Patent No. 200,642, dated February26, 1878 5 application filed v August 16, 1877.

To all whom it may concern:

Be it known that we, JOSEPH BENNOR and PHILANDER POND, of the city andcounty of Philadelphia, in the State of Pennsylvania,

have invented a new and useful Improvement in Adding and RecordingMachines, which improvement is fully set forth in the followingspecification, reference-being had to the accompanying drawings, inwhich- Figure l is a plan view of the machine. Fig. 2 is a like viewwith the case and dial removed. Fig. 3 is an edge view of therecordingregister. Fig. 4. is a like view of the receivingregister.

Like letters of reference in yall the figures indicate the same parts.

The object of this invention is ythe construction of a machine that,after it has recorded, can be set back to any part of its record, andthat, in setting back the register, its record or any part of it will betransferred to a second or receiving register, thus avoiding thepossibility of any part of the record being lost through inadvertence.

Theregister is constructed with two sets or trains of wheels, only oneof which is actuated by the lever. Each wheel of the two sets is rmlysecured to its hub or sleeve, and on the top of each hub is secured adisk, which has on its face numerals 0 to 9, inclusive. They are viewedthrough openings in the dial, and as a disk is revolved each figure isseen in turn until the disk has made one revolution,

i when the adjoining set of wheels are moved one-tenth of a revolution,which is repeated at each revolution of the iirst set, and so on tillthe second set has made one revolution, which, in its turn, carries athird set, to move in the same manner, and so on through the entiretrain. The register thus actuated may have as many sets of wheels as theuse for which it is wanted may require 5 and to prevent the possibilityof adding or recording till its capacity is exhausted, (which wouldresult inthe register commnecing at zero again, and, perhaps, t-he lossof what it had already recorded,) we have constructed the wheel that`carries the disk that records the highest number with teeth cut only inpart of its circumference, so that it cannot make a fullV revolution.Connected with this register, in the same or a separate case, ifdesired, is a second or receiving register, intended to give the footingor addition of the several records transferred from the first registerto this register from time to time. The two registers are similar inappearance, differing only in the parts necessary to operate each.

Referring to the drawings, A represents the base of the machine, and Bthe case. O is the dial, which has openings c c c c, for viewing thefigures consecutively on the disks of the recording-register. E is abell secured to the base of the machine. I, Il, and I2 are studshafts,which have one end permanently connected with the base A, and areprovided at their other end with disks which have numerals 0 to 9,inclusive. F is the lever through which motion is conveyed to theregister and alarm movements. This lever moves on a pin or screw, whichis secured at one 'end to the base of the machine. The other endprojects outside of the case. A pawl, c, works on a pin which projectsfrom the lever, there being a spring, j', attached to the lever, whichholds it to its work. The tooth of the pawl is broad enough to engagethe teeth of the wheels h and j on the shaft I of the unitsdisk. Thewheel h has a shallow tooth cut in base of each of its teeth. G is thebell-hammer lever, which works over a pin secured to the base of themachine at one end, the other end carrying a hammer, which, through suitable mechanism, is made to strike the bell E. On the bell-hammer lever Gis a projection, g, which is kept in contact with the teeth of theratchet-wheel h by means of a spring, f1, said spring being undertension at one end` to the lever G, and at the other end to a pin in thebase of the machine.

On the lever F is a projection, g, which is intended as afriction-piece, to prevent the wheels 7L and j from turning on theircenters more than the distance of one tooth, or onetenth of arevolution, at each actuation of the lever F. Secured to said lever is aspring, f2, under tension, which is secured at its other end to a pin,which projects from the base of the machine. The -use of this spring isto throw the lever F back at the termination of each forward stroke farenough to remove the pawl e from the ratchet wheel or wheels on theunits-shaftof the recording-register, to admit of the train of wheels ofsaid register being moved in an opposite direction when required, fortransferring to the receiving-register, in the manner hereinafterdescribed.

When the lever F is pulled in the direction intended, the pawlc isbrought into contact with the teeth of the wheels h and j, causing themto revolve, and at the moment they have traveled one tooth of theircircumference, or the space of one tooth, the friction-piece g isbrought into contact with the surface of the teeth, and, being broadenough to act on both, prevents them from moving farther than therequired distance. The lever F is limited in its movements by stops ateither side of it, and when,-bythe action of the spring f2, it is drawnback against one of the stops, the pawl e i-s carried beyond the pointof contact with the teeth of the wheels h and j, leaving them free toturn on their axis, as hereinafter described.

The pawl e has /a stop-pin secured to the lever F, which prevents itfrom being thrown out of position by the actionof its spring f, and alsoholds it in position to engage the teeth of the wheels h and j on theforward movement of the lever. rlhe wheel h revolves on the shaft I ofthe units-disk, and is separated by'a collar on said shaft from thewheel j. Secured to and above this wheel j is a plain toothedgear-wheel, 7c, which meshes into a similar wheel, s, on the stud-shaftt, and said wheels meshes intothe wheel o on the unitsshaft of thereceiving-register.

Above the wheel 7c, and on the same hub, is secured a one-toothed wheel,l, which meshes into awheel known as a Geneva stop-wheel,7 (marked m,)which carries the tens-disk. Secured also to these wheels is a disk, x,which has on its face the numerals 0 to 9, inclusive, placed, in tenequal distances, at the outer edge of the disk. The one-toothed wheel Zon the first or units shaft turns the wheel m on the second or tensshaft.

Secured to the wheel m yis a onetoothed wheel, Z', which, in its turn,meshes into a wheel, m', on the third or hundreds shaft. This last wheelm has teeth cut in only part of its circumference, for the purposealready described. l

The descriptionthus far has been confined to that part of the registermore minutely shown in Fig. 3.

Fig. 4, at the other side of the machine, shown in elevation, is thereceiving-register, in which a is a ratchet-wheel with ten teeth. Apawl, a, working over a pin in the base of the machine, engages theteeth of this wheel, to .prevent it from turning only in one direc- Thewheel is secured to the hub or sleeve that carries the units-disk, andrevolves on a pin which projects from the'base of the machine, turningloosely on the sleeve; and above the wheel n and between it and theratchet-wheel p, which forms a collar for it, is a toothed or gearedwheel, o, which engages in the wheel la in the recording-register.

Above the Vwheel o, and secured to the'same hub it turns on, is aratchet-wheel, p. A pawl, e2, swinging on a pin in the wheel o, engagesthe ratchet-wheel p, so that if the wheel o is rotated in one directionits motion is communicated by means of a pawl, e2,- to theratchet-wheelp; and if turned in the opposite direction, the pawla engages the wheel u, and prevents the hub, with all its wheels, frommoving'in that direction. Above the ratchetwheel p', and secured to thesame sleeve, is a one-toothed wheel, q, which, in its turn, engages aGeneva stop-wheel, r, on the tens-disk hub. On this hub, and secured tothe wheel r1, is another wheel, Q1, which, in its turn, engages a wheel,r, on the hundreds-disk hub., This wheel also has a wheel, Q2, securedto it, which engages a wheel, r2, on the fourth stud, or thousands-disk.All the wheels on each stud are secured toa sleeve, and on-the top ofeach is fastened a disk, x, having thel numerals() to 9, inclusive,arranged in the order of numerals, and in the direction in which thewheels turn. A screw or pin in the top of each post keeps the wheelconnected therewith in its place. A dial, C, surmounts the whole, andhas openings c c c c, large enough to admit of one figure only appearingat each opening. The gear-wheel s meshes in the wheel o, and is loose onthe shaft t, turning between a collar, u, and the ratchet-wheel o, bothof which are firmly secured to the shaft. On the `wheel s is a pawl, s',which moves on a pin secured to said wheel, and engages the ratchet t.The end of the shaft t is squared to receive a key.

The operation `of the machine is as follows: Pull the lever F from itsplace of rest in the direction it will move until it comes to a stop.rEhe result will be that the pawl e will, in its traverse, engage atooth in each of the ratchetwheels h and j, which will turn on theircenters, and as they turn, the projection g on the lever G, being incontact with the wheel h, will be raised, and, at the completion of thestroke ofthe lever F, carried over the highest point of the tooth, andfall into the recess formed by the next tooth, thereby causing thehammer on the end of the leverGto strike the bell E and sound the alarm.The wheel h has a notch formed in the back of each of its teeth, whichserves as a catch to hold the bell-hammer lever, and prevent the hammerfrom striking the bell in case the lever F is permitted to return to itsplace of rest after having been moved only a part of its stroke.

-The notch is intended to be formed near the root of the tooth, so thatif the lever F is not moved asufficient distance to raise the projectiong on the bell-hammer lever Gr over the notch, then the recoil will nothave sufficient force to vibrate the lever enough to strike the bell.

Instead of the wheel h having notches or fine teeth cut in the back ofits teeth, there may be substituted a ratchet-wheel with flue teethsecured to the wheel h, and a pawl made to fall into the teeth as thewheel revolves, to hold it from turning back.

The lever Gis drawn back to its place of rest by the force of the springf1, and the pawl e will ride over the teeth of the wheel h, which isprevented from moving backward by the projection g engaging in theshallow or main teeth of the wheel h, already described.

Thus it will be seen that the teeth of the wheel h become guides to thepawl to ride upon in its backward movement, and prevent it from draggingover the teeth of the wheel j, which wheel would turn backward if itwere not for this shield of protection.

The operation of the lever, as described, rings the bell, and at thesame time causes the wheel j to turn on its center, turning the hub towhich it is secured, and carrying with it the units-disk the distance ofone tooth, or one-tenth of its circumference, causing the ng ures" tochange, and increasing the register one unit. This is repeated as oftenas the lever is pulled until the one-toothed wheel l engages the Genevastop-wheel m on the tensdisk hub. The moving of this wheel one toothincreases the record one, when the cipher (0) appears on the units-disk,making ten. This is continued at each actuation of the lever till thehundreds-disk has recorded as far as it can turnthere being a stopformed in the wheel by cutting teeth only in part of its circumference,thus preventing the one-toothed wheel on the tens-disk from turning, andconsequently stopping the register.

The gear-wheel lo moves with the units-regis tering wheel, as beforeexplained, and as it meshes in the gear-wheel o on the units-hub of thereceiving-register, this wheel consequently turns with it; but as thewheel o is loose on its shaft, and as the motion it receives is in acontrary direction to that required to engage thepawl e2 with theratchet-wheel p', it will readily be seen that it will turn withoutmoving the receiving-register.

If a key is applied to the square cn the end of the shaft of the wheels, and turned in the direction to reverse the motion of therecording-register, the ratchet c will engage the pawl s', and the wheels be made to turn, which will trnn the wheel 0 on the unitshub of thereceivdng-register in the direction to engage the pawl s with thcratchet-wheel p 5 and as the ratchet-wheel is secured to the hub thatcarries the unit-registering wheel and disk, and as the wheels k o areof the same diameter and have the same number of teeth, it will followthat they make the same number of revolutions in the same time 5 and asthe figures on the tens-disk of the receing-register are placed in areversed order to those in the recordingregister, it follows thatwhatever num ber the recording-register is turned back thereceiving-register will show in its record. In this way any part or thewhole of the record of the recording-register may be transferred. Thetwo registers may be connected by an intermediate wheel, set so as tomesh in both of the wheels 7c o.

The operation of the receiving-register is the same as that alreadydescribed for the record ing-register. The lever F may be hun g in thecenter, and both ends project through the case of the machine, and theregister operated at either end of the case.

That we claim as new, and desire to secure by Letters Patent, is

The combination of the receivingregister with the recording and transferregister by means of the gear-wheels k, 0, and s, ratchetwheels a and c,and the pawls el and s', or their equivalents, whereby thereceiving-register is permitted to remain in a state of rest while therecording-register is turned in one direction for recording, but iscaused to turn simultaneously with the recording-register, to receivethe transfer, when the recording-register is turned in the oppositedirection, substantially as set forth.
